Ink Review #297: Robert Oster Viola


Robert Oster Viola is an unusual but interesting purple. It reminds me of lilacs in the spring. I purchased my sample of ink from Vanness Pens


The color:

Viola is a light, spring purple.



There is a strong blue undertone, which pools up in large swabs.


Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 15 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: None

Other properties: medium shadingno sheen, and no shimmer

On 20 pound copy paper the ink performed well, no issues that I noticed.

Comparison Swabs:

Ink swabs for comparison, left to right (top to bottom for mobile RSS): Robert Oster Australian Opal Mauve, Robert Oster Viola, and Robert Oster Violet Clouds. Click here to see the Robert Oster inks together. Australian Opal Mauve is a bit darker than Viola.


Longer writing: 

I used a medium Pelikan M400 White Tortoise on Tomoe River paper. The ink had an average flow.


Overall, it's a interesting color. It's not one that I've seen before in other brands, which is great. I love that it has some interesting shading.
